A Guide to Open Source for IT Practitioners

It’s easy to see that open source is changing the way people think about infrastructure. However, as the saying goes: “The future is here, it’s just not evenly distributed”. As is normal, there will always be pockets of IT where active involvement in open source will just take some more time.

I’ve worked on open source for a few years now, and I have always wanted to publish a post that focuses on a few key ideas that I wish I could tell every new entrant into the world of open source. I feel like going in with the right expectations can really help any efforts here go much more smoothly. So if you’re accustomed to getting most if not all of your technology stack from a vendor, and you’re wondering about the open source craze, and trying to make sense of it all, this is for you. My goal with this post is to empower you to start getting out there and exploring the various communities behind the projects you may already have your eyes on.

Open Source is “Free as in Puppy”

Before some practical tips, I want to spend some time on expectations. This is crucially important Continue reading

What is a hypervisor?

Hypervisors often get overlooked as a technology in favor of the flashier concept of virtualization, but you can’t get to the fun of virtualization until you understand what a hypervisor does within a computing system.While the benefits of virtualization and cloud computing may now seem like old hat within the IT infrastructure, that wasn’t always the case, and it is hypervisor technology that has helped drive innovation in the world of cloud computing.Hypervisor definition A hypervisor is a process that separates a computer’s operating system and applications from the underlying physical hardware. Usually done as software although embedded hypervisors can be created for things like mobile devices.To read this article in full, please click here

Worth Reading: Big Software Failure

Why would anyone undertake a multi-year software project today? Or upgrade an in-house-hosted legacy application? Or build—or use—anything that behaved like a monolithic software application? Big software project failure data is legendary.11 There are myriad horror stories with titles like “9 VERY Scary ERP and ERP System Implementation Statistics.”12 The Standish Group actually labels their annual technology project analyses as “Chaos Reports.”14 They reported that 66% of all technology projects completely or partially failed in 2015. —Stephen J.

BrandPost: SD-WAN: Why DIY + Co-Managed Approach is a Win-Win

The SD-WAN market continues to experience phenomenal growth. A September 2017 IDC SD-WAN survey highlights that 75 percent of U.S. enterprises plan to adopt an SD-WAN solution in the next two years. Enterprises are eager to embrace and deploy SD-WAN solutions because they provide many important benefits such as improving network and application performance and availability, reducing branch office complexity, lowering bandwidth and operational costs, and improving the performance of directly connecting users from branch locations to cloud-native applications.Today, enterprises implementing an SD-WAN solution can choose between a do-it-yourself (DIY) approach or selecting a managed SD-WAN service from a managed service provider (MSP). The DIY approach is appealing to enterprises that have in-house expertise in managing their WAN network environment and have invested the time to evaluate and select an SD-WAN solution that addresses their connectivity requirements. In this model, enterprises procure, own, deploy and manage the SD-WAN equipment, software and network connectivity in-house.To read this article in full, please click here

Juniper implements its VXLAN routing solution using asymmetric mode and some symmetric. With these different routing solutions, these vendor switches can’t operate Continue reading

Top 10 data center predictions: IDC

IDG The lifecycle of a data center is measured in decades, yet the tech that’s inside is changing constantly.“Today’s data centers are really out of sync with the equipment that’s inside them. It would be like using the enclosure for a 1984 Macintosh with the current generation of iMac. It just doesn’t jive very well. The power, cooling and space requirements have all morphed,” says Jennifer Cooke, research director for IDC's datacenter trends and strategies teamTo read this article in full, please click here
